How to turn off full-screen mode on Xiaomi TV: a detailed guide

Full-screen mode on Xiaomi TVs often turns on accidentally — just one wrong tap on the remote or a malfunction in the application, which disappears the control panel, hides the interface elements, and the picture stretches to the entire screen, preventing comfortable viewing, especially when working with MIUI TV, when you need to quickly change the channel or open the settings, but all the buttons of the remote are ignored.

In this article, we’ll look at all the ways you can get out of full-screen, from standard keyboard shortcuts to hidden functions in the engineering menu, nuances for different models (Mi TV 4S, Mi TV Q1, Redmi Smart TV) and firmware versions, and why mode sometimes turns on spontaneously, and if your TV freezes in full-screen and doesn’t respond to commands, here you’ll find a solution.

Why Xiaomi TV is going full screen

Most often, the problem arises from automatic zoom, a feature that adjusts the image to the screen size. On Xiaomi TVs, it does not work perfectly: when switching the signal source (from HDMI to TV or vice versa), the system can “forget” previous display settings.

• 🎮 Game consoles (PlayStation, Xbox) – they often force full-screen mode to activate via a video game. HDMI-protocol.
• 📺 Satellite receivers – some models send a signal to the TV to format the screen.
• 🔄 Firmware updates - after the update, user scale settings are reset (relevant to the MIUI TV 3.0+).
• 🖱️ Mouse/keyboard connected via Bluetooth – Accidental pressing F11 win+Shift+Enter may be able to activate the mode.

On the Redmi Smart TV X and the new Google TV models, the problem is exacerbated by a conflict between Xiaomi’s shell and Google’s services, such as when launching YouTube or Netflix, the system can automatically stretch videos, ignoring user settings.

Method 1: Standard combination of buttons on the remote

The fastest method is to use hotkeys, and most Xiaomi remotes (including the Mi Remote and Redmi Remote models) have a combination of:

Press and hold for 3 seconds: [Menu] + [OK]

If this doesn’t work, try alternatives:

• 🔘 [Back up] + [Home » News » Hold for 5 seconds (for Mi) TV Stick and consoles).
• 🔄 [Loudness -] + [Loudness +] — Press and hold for 2 seconds at the same time (works on Mi). TV 4A).
• 📺 [Source] + [OK] — If the full screen mode is activated when changing the input.

On voice-controlled remotes (a button with a microphone), sometimes double tapping on [Voice search] helps, which resets the current display mode. If the buttons don't respond, check the batteries or reset the remote with the batteries out for 10 seconds.

Make sure the batteries are charged.

Try another remote (if you have one).

Point the remote directly to the IR receiver of the TV.

Hold the buttons for at least 3 seconds-->

Method 2: Setting the screen in the TV menu

If the hotkeys don't work, you'll have to manually change the display settings.

1. Press [Menu] on the remote and select Settings → Screen and sound.
2. Go to Screen Mode (or Image Format on Old Firmware).
3. Choose one of the options: Standard — retains the original proportions, stretch — forced fullscreen (probably already active), the size of the screen is the best option for most cases, user — allows you to manually adjust the scale.

Save the changes and check if the problem has gone away.

On Google TVs (such as Mi TV Q2), the path is different:

Settings → Display and sound → Screen size → Scale reset

Method 3: Reset image settings via engineering menu

If the standard methods don't work, you'll have to use a service menu, which is a good way for power users, because incorrect changes can disrupt the TV.

Instructions for Mi TV based on Android TV:

1. Turn on the TV and plug in. USB-keyboard.
2. Press sequentially (with intervals of 1 second): Settings → Device → About TV → Click 5 times on “Model” After that, the developer menu will open.
3. Return to the main menu and go to Settings → Device → Developer settings.
4. Activate the debugging option via USB.
5. Connect the TV to the PC via USB and use ADB-Adb shell settings put global policy_control immersive.full=* This command will reset all forced full-screen settings.

For PatchWall TVs (Indian versions), the path is different:

Settings → Account & Security → Developer Options → Force Fullscreen

💡

Before working with the engineering menu, back up your settings through Settings → System → Backup. This will allow you to restore the settings if something goes wrong.

Method 4: Update firmware and reset to factory settings

If a full-screen mode is due to a software failure, a software update or a full reset will help.

1. Go to Settings → About TV → System Update.
2. Click Check Updates and install the latest version (if available).
3. After the update, reboot (Settings → System → Reboot).

If the problem persists, do a soft reset (does not delete applications and data):

Settings → System → Reset → Resetting image settings

In extreme cases, make a full reset to factory settings (remove all installed applications and accounts):

Settings → System → Reset → Reset all settings

💡

Factory resets should be the last option, and then you have to reconfigure your Wi-Fi, accounts and screen settings.

Method 5: Hardware reset (if the TV doesn't respond)

If the TV is completely frozen in full screen and doesn't respond to the remote or the buttons, you'll have to do a hardware reboot.

1. Find the Reset button on the back of your TV (usually next to HDMI or USB connectors).
2. Take a paperclip or toothpick and press the button for 10-15 seconds.
3. Turn off the TV for 1 minute, then turn it on again.

💡

If full screen only turns on when a particular device is connected (such as consoles), check its settings - perhaps the problem is on the signal source side, not the TV.
